How To Create New Root Filesystem From New Kernel Rev

meg

Other Parts Discussed in Thread: AM3517

I have an AM3517 Experimenter. Need to upgrade kernel from 2.6.32 to 2.6.33.

Previously able to make 2.6.32 SDK based kernel SD card and boot. This is using ext3 root file system supplied by 5.0 SDK.

Successfully configured and built 2.6.33 kernel uImage and copied to SD card. The kernel loads and runs but fails somewhere during loading drivers.

Suspect this may be because a new file system based on 2.6.33 has not been generated and installed on SD card.

What is the recommended procedure to generate a root file system from a new general distribution for this AM3517 Experimenter target?

Seems like new root file system needs to be generated from 2.6.33 source - correct?

Busybox? Buildroot? Other?

Thanks

Changing from 2.6.32 to 2.6.33 shouldn't require a new file system. You probably need to install the kernel version specific modules on your file system. Something like:

make modules ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
make modules modules_install INSTALL_MOD_PATH=/media/your_sd_card ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

You should see "/lib/modules/2.6.33.*" on your SD card. You might have to be "root" to install to SD card. Assumes cross-compiler has been pathed in.

What SDK are you using? There is no SDK version 5.0 for AM3517.

I probably mis-labeled what I'm using. The 5.0 I was referring to was CCS version, not the SDK. The SDK is 04_01_00_00 found here
